A GENERAL SYNTHETIC APPROACH TO OPTICALLY ACTIVE IRIDOID AGLYCONES. THE TOTAL SYNTHESES OF β-ETHYL DESCARBOMETHOXYVERBENALOL, ETHYL CATALPOL, AND (-)-SPECIONIN

A general approach to the synthesis of iridoid aglycones is reported.A combination Claisen rearrangement/nitrile oxide cycloaddition sequence has permitted the facile annulation of a highly functionalized cyclopentane ring onto a simple glycal derived fro

COMBINATION CLAISEN-NITRILE OXIDE ANNULATION. A STRATEGY FOR RING CONSTRUCTION WITH RIGID STEREOCONTROL DICTATED BY AN ALLYLIC HYDROXYL GROUP.

A new method for annulation of rings onto existing allylic alcohol derivatives is presented.The sequence involves Claisen rearrangement followed by nitrile oxide-olefin cycloaddition.Control of relevant stereochemistry is emphasized.
